A bearer processing system enhances network communication by dynamically adjusting bearer configurations based on quality of service (QoS) requirements. The system addresses the problem of inefficient data transmission when a data service's QoS needs do not align with the current bearer's capabilities, leading to suboptimal performance or resource waste. The system includes a rule that maps data services to specific QoS parameters, ensuring that each service is transmitted with the appropriate QoS settings. When a data packet is received, the system checks if the QoS requirements for the associated data service match the QoS of the current bearer. If they do not match, the system triggers a bearer modification to align the bearer's QoS with the service's needs. The system also includes a processor that matches incoming data packets to the appropriate rule by identifying the required QoS information for the corresponding data service. This ensures that data is transmitted efficiently and reliably, improving overall network performance.

The system includes a first processor and a first program that generate a bearer processing indication, which contains an event identifier corresponding to the type information description of the data service requiring processing. A second processor and a second program then use this event identifier to determine the data service type of the incoming data packet. Specifically, the second program causes the second processor to first identify the type information description associated with the event identifier. It then uses this type information to determine the data service type of the data packet. This approach allows for flexible and scalable processing of data services by leveraging event identifiers to map data packets to their respective service types, improving efficiency and adaptability in bearer management.

The system includes a gateway control unit (GW-C) and a gateway user plane unit (GW-U) that work together to track traffic data for specified bearers. The GW-C sends a traffic query request to the GW-U, instructing it to collect statistics about the traffic of a particular bearer. The GW-U then monitors the bearer's traffic, generates statistical results, and sends them back to the GW-C. If the GW-C determines that the accumulated traffic data for the bearer remains unchanged over a specified time interval, it deletes the bearer to free up network resources. The GW-U is responsible for collecting and reporting the traffic statistics, while the GW-C processes the results and makes the deletion decision. This system ensures efficient bearer management by automatically identifying and removing inactive bearers, thereby improving network performance and resource utilization.

This invention relates to a gateway user plane (GW-U) in a wireless communication system, specifically addressing the challenge of dynamically managing quality of service (QoS) for data services. The GW-U is configured to process data packets and apply rules that define correspondences between data services and QoS requirements. When a data packet is received, the GW-U identifies the associated data service and retrieves the required QoS information from a predefined rule. The system then compares this required QoS with the QoS parameters of the current bearer used for transmitting the data service. If a mismatch is detected, the GW-U determines that a trigger condition is met, indicating that the existing bearer may not adequately support the service's QoS needs. This mechanism enables dynamic adjustments to bearer configurations to ensure optimal service delivery.

The GW-U receives data packets from a user equipment (UE) and processes them according to bearer processing indication information. This information includes an application identifier, which specifies the data service type matching the data packet, allowing the GW-U to apply appropriate processing rules for that service. Alternatively, the bearer processing indication information may include an event identifier corresponding to type information that describes the data packet, enabling the GW-U to handle the packet based on the associated event type. The GW-U then forwards the processed data packet to a core network or another network entity. This approach enhances network efficiency by enabling dynamic and context-aware packet processing, ensuring that different data services or events are handled according to their specific requirements. The use of application identifiers or event identifiers allows for precise control over how data packets are managed, improving overall network performance and service quality.

This invention relates to quality of service (QoS) management in an evolved packet core (EPC) network. The problem addressed is ensuring that data services receive appropriate QoS treatment by dynamically managing bearers in the EPC. A gateway control (GW-C) system monitors QoS information for all existing bearers in the EPC. When a data packet is received, the system checks whether any existing bearer has QoS parameters matching those required by the data service associated with the packet. If a matching bearer is found, it is updated to ensure its QoS parameters align with the service requirements. If no matching bearer exists, a new dedicated bearer is created with QoS parameters that match the service requirements.

This invention relates to quality of service (QoS) management in wireless communication networks, specifically within an evolved packet core (EPC) architecture. The problem addressed is the efficient allocation of QoS resources based on the type of data service being transmitted, ensuring optimal network performance and user experience. The invention involves a gateway control plane (GW-C) component in a 5G or 4G network that processes data packets. The GW-C includes a processor executing a program with instructions to determine the data service type of a packet based on bearer processing indication information. Once the service type is identified, the GW-C either allocates QoS parameters accordingly or receives pre-allocated QoS parameters from another EPC network element, such as a policy and charging rules function (PCRF) or a mobility management entity (MME). This ensures that different services (e.g., voice, video, or data) receive appropriate QoS treatment, improving network efficiency and service quality.
